Potasium Nitrate

The Solubility of Potassium Nitrate Introduction The drive of this travail out was to remark how temperature affected the solubility of solid thou process that was dictate in opposite re answers. The temperature was non the other occasion that was cosmos varied to observe the solubility of potassium nitrate, the mensuration solute was to a fault varied and the kinds of solvents in this investigate were varied. The temper of each solvent limitings due to the common ion effect which is essentially means that the parsimony of a soluble salt is cut back if there is a common ion with that salt. Also potassium nitrate solubility in basic and acidic places was also determined, to discern if it affected the temperature. The moles of KNO3 s/ Kg solvent were needed to anticipate the correct molal closeness. Another goal or purpose of this experiment was to take the heat of solution of each of the different concentrations. The inverse temperature and a additive pl ot of the molal concentration were needed to steer this. The linear equation needed to calculate this was In(s)= -(? H/ 2R)(1/T)+(1/2) where R is a constant and T was the temperature. The linear regression molding could also be use to rocky the heat of solution.

Where purpose the heat of solution could be primal is when we are stressful to figure out the enthalpy change of a solution. Procedure The mathematical functions for this experiment were followed as those printed on pages 221-223 of the manual, experiment number 36 (see references). Deviations in this experiment from the what was printed in the pro cedure was that Microsoft excel was needed t! o give birth the graph instead of using the graph paper provided at the end of the experiment. data and Results The first eight graphs show the relationship between the temperature of the solution and the nature log of each specialised molal concentration. The NaOH and HCl solvent results were taken from the personal experimental observations not from the averaged results of the...If you want to overprotect a full essay, order it on our website: OrderCustomPaper.com
